Thread: Updated and Optimized Ubuntu Free Graphics Drivers

  1. #311

    Before I go back to the bug saying that the fix doesn't work, is it really included in the latest driver packages?

    The versions on my machine are

    $ dpkg -l|grep radeon
    ii libdrm-radeon1 2.4.34+git1205110954.86451a~gd~p Userspace interface to radeon-specific kernel DRM services -- runtime
    ii xserver-xorg-video-radeon 1:6.14.99+git1205111032.4b9bad~gd~p X.Org X server -- AMD/ATI Radeon display driver
    The linked bug is an xserver bug, for which I don't provide packages. You have to search (and eventually file a new one) bug for this in launchpad and follow there.

    Hi oibaf,

    i915 and i915g both don't seem to work anymore. Instead i get llvmpipe and /usr/lib/dri-alternates doesn't exist anymore.

    glxinfo shows this:

    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
    OpenGL version string: 2.1 Mesa 8.1-devel (git-c2f1fbf precise-oibaf-ppa)
    OpenGL shading language version string: 1.20

    @derdestiller: compiz on a 915GM is still working for me with the PPA. Not yet tried other programs, but glxgears was indeed stuttering when I last tried it.

    This is what i get:

    libGL: screen 0 does not appear to be DRI2 capable
    libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/tls/swrast_dri.so
    libGL: OpenDriver: trying /usr/lib/i386-linux-gnu/dri/swrast_dri.so
    libGL: Can't open configuration file /home/reddevil/.drirc: No such file or directory.
    I'm not sure, but as far as i can tell i didn't change anything relevant from my previous working configuration.

    Removing the PPA and adding it again solved my problem.

  7. #317

    Default Update

    Mesa in the PPA now uses LLVM compiler for the r600 driver.

    Default graphical glitches since last update (LLVM for r600)

    First, thank you oibaf for your excellent work about packaging those drivers to provide an easy to use ppa.

    I'm using it for several month now with an AMD radeon HD 6950 (2GB). I can play lots of games with good fps (even unigine oil rush is running fine in medium details in 1920x1200).

    But, unfortunately, since the last update (where mesa in the ppa uses llvm for r600), I encounter severe graphical glitches for every 3D application (2D desktop and videos are fine).

    Here is a screenshot of glxgears :



    I'm currently using ubuntu 12.04 64bit, unity 2D. Below are some glxinfo :

    OpenGL vendor string: X.Org
    OpenGL renderer string: Gallium 0.4 on AMD CAYMAN
    OpenGL version string: 2.1 Mesa 8.1-devel (git-6404095 precise-oibaf-ppa)
    OpenGL shading language version string: 1.30

    I tried to revert to original distribution packages, wich solve the rendering problem, but cause performance and compatibility problems of course...

    So I brought back the ppa and the faulty rendering is still here.

    Have you got an idea to diagnose this problem ?

    i can't play a full game without crash the oibaf ppa is broken for hon right now.

    it just crashes randomly...

    now i tryed the openGL renderer instead of the directX one now it does not crash.

    means the bug is a wine/directX bug with the radeon driver ..
